My grid heaters are switchable on-off. Use them when I need them, not often. Just put a switch in the control line for the grid heater relays, easy to do.

 

I'm looking to get rid of mine to enhance air flow into the motor.

 

If you live in Southern Utah, I wouldn't consider any minor increase in airflow to be an acceptable tradeoff for loss of the grid heater function. I live on the Texas Gulf Coast and my truck still has the grid heater.

I thought the ECM turned them on when they are needed and off when they are not. Why put more wires on it???? To each their own!

I'm going to go out on a limb here and say that you will not see any difference what-so-ever. It is not going to spool your turbo any faster than it does now, at least you won't be able to tell, and as far as EGT's, I'll bet it doesn't make 10 deg difference.

 

It's worth a try. I learned along time ago that stock isn't always better, but sometimes it is. In this case I'm going to find out, after I dyno both ideas I'll post and let you know the results.

 

Please do! I'm curious to what you'll find.

 

As far as I know, no comercial application of the b-series has grid heaters. The heaters were something that dodge added to meet cold start emissions.

 

a buddy of mine had a 2nd gen with a comp and 155bd injectors and custom airfilter and he removed the grid heater and dynoed over 1000ft lbs,cant remember the hp,he swore by removing the heaters to get maximum airflow,i may try it in the summer months,like was said before, cant hurt

 

Hopefully in the next couple of weeks I can get Richard "MADDOG" Madsen to fire up his dyno. then we'll see!

 

This experiment has been done before.

I'll bet $20 you will see 0.0 increase in HP on the dyno from removing the grid heaters.

You are not pushing enough air that it will make a difference.

 

i dont think your going out on a limb. I dont think he will see a difference either!

 

id bet $20 that he wont see any increase either!

 

may not show up as a hp gain but maybe slightly cooler egts from less restriction,cooler air is better air.still gonna try it this summer.

 

I have no problems starting down to 15* (hasn''t been colder here) with my nonfunctioning grid heaters and not being plugged in.

 

Unless you are pushing a ton of air with twins or a very large single, I bet the decrease in EGTs are hardly measurable. JMHO
